Destination Numbers; Direct Dial-In To Endpoints Or Dma Vmr Using Automatically Generated - Polycom RealPresence 1500 Administrator's Manual

Gateway Calls
Dialing from ISDN/PSTN Endpoints
Dialing String and Call Flow from ISDN Endpoint to IP Endpoint
[GW Profile ISDN/PSTN number] - The dial-in number assigned to the Gateway Profile, including the
required country and area codes.
For example, if the dial-in number assigned to the Gateway Profile is 5705555, enter this number with the
appropriate area code: 2125705555.
Once the participant is connected to the Gateway Profile and hears the IVR message requesting the
destination number, using the DTMF input keypad, the participant enters the number of the destination
endpoint followed by the # key. For example, enter 3456# for IP endpoint.
To enter an IP address as the destination number, replace the periods (.) with asterisks (*) in the format
n*n*n*n followed by the # key. For example, if the IP address is 172.22.188.22, enter 172*22*188*22#.
PSTN Dial-in Using GK Prefix
When connecting to an Collaboration Server that is standalone or part of a DMA solution deployment, PSTN
participants are prompted by an IVR message requesting the Destination Conference ID followed by the
# key to be entered using the DTMF input keypad.
Including the Gatekeeper Prefix in the DTMF input string enables PSTN participants to use the input string
when connecting to an Collaboration Server whether the Collaboration Server is a standalone MCU or part
of a DMA solution deployment. For a detailed description, see PSTN Dial-in Using GK Prefix.

Direct Dial-in to Endpoints or DMA VMR using Automatically Generated

Destination Numbers

ISDN/PSTN participants can call the destination endpoints without interaction with the IVR of the gateway.
This dialing method is enabled when the administrator configures the Gateway Profile to automatically
generate the dial string of the destination endpoint or Meeting Room on the DMA by truncating the dial in
string and replacing the truncated digits by other digits that can be used as the destination number.
For a detailed description of the call flow when dialing the DMA using this method, see Calling a
RealPresence DMA Direct with Automatically Generated Destination Dial Strings.
Calling an IP Endpoint via Gateway
If the call destination is an IP endpoint, the endpoints must be registered to the same gatekeeper to which
the Collaboration Server is registered. There should be a mapping between the dial-in numbers in the range
defined for the ISDN Network Service and also assigned to the Gateway Profile and the IP endpoints, in
such a way that the alias of each endpoint is the number that will be appended to the ISDN prefix.
